Ok, so i am an old man on a dirt bike......... so what! i have a 01 KDX220, and has enough vibration in the bars to put my hands to sleep pretty quick! i replace the exh. o-rings every four rides. the pipe mouts appear ok. I have "adjusted" the pipe to fit. still the stock bars, and i have added bark busters. Now I feel that since the bark buster add-on, this may have made it worse, by adding more weight to the end of the bars. the bark busters have saved my wrinkly ole hands many times, and i think i need to keep them, but the vibration! aaaarg! faast makes a three piece bar i have been thinking about, but $$$$ so where to with this?? help me out here fellas! :whiner: :worship: :worship:
